Electronic Parking Brake (EPB) System reset is a commonly performed special function. You can use this function to reset the electronic parking brake system and brake pads (retraction, release of the brake pump), G-sensor and body angle calibration. This function has multiple uses and can safely and effectively maintain the electronic brake system. These applications include deactivating and activating brake control systems, assisting in controlling brake fluid, applying and releasing brake pads, setting brakes after replacing brake discs or brake pads, etc.
If the brake pad wears the brake pad sense line, the brake pad sense line will send a signal to the onboard computer asking for replacing the brake pad. After replacing the brake pad, you must reset the brake pad to clear the trouble code.
Otherwise, vehicle will continue to falsely notify the driver that the brake pads are in need of replacement.
A reset must be performed in the following cases
● The brake pad and brake pad wear sensor are replaced.
● The brake pad indicator lamp is on.
● The brake pad sensor circuit is shorted.
● The servo motor is replaced.
